This invention relates to dispensing devices and is illustrated herein as embodied in apparatus developed for applying a coatin'g of a heavy viscous cement to a strip of fabric.

Letters Patent of the United States No. 1,771,388, granted July 22, 1930 on an application filed inthe name of the present applicant, and applicants copending appl1 cation Serial No. 468,01? filed July 15, 1930, disclose apparatus which is in successful use in applying an adhesive having a very high viscosity and commonly spoken of as dough to the surface of a strip of previously coated duclr used in the ,manufacture of gemand economy insoles by the cold process. it is an object of the present invention further to improve dispensing apparatus of this character and to provide such an apparatus well adapted to receive and to facilitate the handling of large commercial containers of acihesive, larger than can conveniently be used connection with the apparatus disclosed in the patent and the application above referred to Thus the illustrated apparatus is arranged to receive a large can or drum of adhesive, which is supported in such a manher that it can be swung into inverted position so that the adhesive can pass through the open end'of the can or drum and through the nozzle of the apparatus directly to the surface of the sheet material on which it is to be spread.

To this end, and in accordance with features of the invention, the illustrated apparatus is provided with a stationary frame to which is trunnioned a swingable frame adapted to receive an open-ended drum or other large container of adhesive and wlth a nozzle, one end of which conforms to and receives the open end of the container and the other end of which receives the stu or strips of material to which the coating 1s to be applied. This nozzle may advantageously be provided with mechanism for controlling the thickness of the coating 1n the manner disclosed in the Nash Patent No. 1,771,- 388, In the preferred machine, in accordance with another feature of the invention, simple mechanism, illustrated as toggles, is

utilized to clamp the nozzle to the container and the nozzle and container to the swingable frame. After the parts have been secured together in this fashion, with the open end of the container up and with the nozzle secured thereto, a strip or strips of fabric are passed across the nozzle. T he swingable frame, to-' of the invention a latch is carried by the sta- I tionary frame of the illustrated apparatus and cooperates with the swingable frame to maintain the swing-able frame either in container-receiving position or in inverted operh ative position as may be desired. in accorciance with still another feature, the strip engaging portion of the nozzle is provided with a bar or plate hinged at one side of the and normally maintained in operative position by a latch at the other side of the nozzle,

and thus supporting the strip material as it is pulled past the nozzle but permitting the plate to be easily swung away from the nozzle when the. container is positioned nozzle upwardly. This construction permits a new strip or strips to be readily supplied, after which the plate is returned to and latched in operative position so that, upon inversion of the swingable frame, the container and the nozzle, the strip material may be pulled past the nozzle and thereby receive a coating of adhesive.

in order to economize on strip material and at the same time to reduce the number of dispensing devices which are necessary, the present apparatus is made to receive two strips of material which may be of diflerent widths, selected with a view tothe widths of the insoles in the manufacture of which each individual dispensing device is to be used. As illustrated and in accordance with a feature of the invention, these two strips are pulled through a single slot in the nozzle, a removable closure illustrated as a block being used to separate the slot into two parts,

one for each strip of material. Thus by using one or another of a series of closures of different lengths the dispensing apparatus may be adapted to receive strips of fabric of different widths. Normally a closure will be used such that the apparatus will handle two strips one of which is somewhat narrower than the other, the narrower strip being used in the manufacture of smaller insoles and the wider being used in the manufacture of larger insoles.

With the above and other objects andfeatures in view, the invention will now be described with reference to the accompanying drawings and pointed out in the claims.

In the drawings,

Fig. 1 is a perspective view of coating apparatus embodying the .present invention and showing the parts in operative position;

Fig. 2 is a perspective view, lookin down upon the apparatus, with most of t e normally stationary frame omitted, showing the container positioned open end upward, with the nozzle in place, and with the hinged stripsupporting plate swung upwardly so that strips of material can conveniently be positioned in operative relation to the nozzle;

I viewpoint at right angles to that from which Fig. 3 is an elevational view of the apparatus with the container positioned open end upward;

Fig. 4 is an elevational view taken from a Fig. 3 was taken, showing the apparatus on a smaller scale than Fig.,3,'and showing also a roll of strip material suitably supported and passing across the nozzle, ready for the inversion of the swingable frame, the container and the nozzle into operative position; 5 is an elevational view of the strip receiving portion. of the nozzle in operative position;

Fig. 6 is a transverse section, substantially on the line VIVI of Fig. 5, but on an enlarged scale, of a portion of the nozzle taken through the block which separates the slot of the nozzle into two parts to receive two strips of different widths; and

Fig. 7 shows a tool which may be used to punch a hole in the bottom of the container,

after the swinging frame, the container and the nozzle havebeen inverted, to admit air to the container so that the adhesive will not be retained in the inverted container by at-. mospheric pressure. I

The principal parts of the illustrated apparatus comprise a stationary frame 10 the upper end of which is .open and on which is mounted a swingable frame 12 arranged to carry a large can, drum-or other suitable container 16 for adhesive and a nozzle 18 secured to the open end of the drum and to the swinging frame past which strips 20 of cotton duck are pulled so that a coating of adhesive 22, contained originally in the drum the nozzle 18, is applied.

The frame 10 comprisesa base portion 24 having a pair of upstanding arms 26 to which is trunnioned, as shown at 28, the approximately U-shaped swingable frame 12. In order to prevent tilting of the drum 16 relatively to the swinging frame when the drum is positioned open end upward, asillustrated in Figs. 3 and 4, but before it has beensecured in place, a transverse member 30 (Fig. 1) is secured to the bar of the U-shaped swinging frame, the two last-mentioned parts forming a seat for the drum 16.

One end of the nozzle 18, which may be a casting of, for example, aluminum, is made serves to form an air-tight seal between the two. The nozzle 18 is also provided with two pairs of lugs 34 placed to receive between them and to slide on the normally vertically extending arms of the swingable frame 12, thus restrainin the nozzle from transverse movement relatively to the swing-. ing frame. Means, illustrated as a pair of adjustable toggles 36, is provided for securing the nozzle 18 to the drum 16 and the nozzle 18 and drum 16 to the swingable frame 12 after the parts have been assembled and while the frame 12 is positioned open end up. Each toggle 36 comprises a pair of links 38 (best shown in Fig. 2) pivoted at one end to the nozzle 18 and connected at the other end to a pivot member 40 into which is threaded a screw 42, the head 44 of which is elongated and arranged to cooperate with a 'hook-sha ed portion 46 provided at the end of eac of the arms of the swingable frame 12. When a drum 16 has been placed in the swinging frame 12, open end upward, and the nozzle 18 has been placed upon it, the toggles are swung into upstanding position with their heads 44 beneath the hook members of the swingable frame 12, and the pins of the toggles are forced respectively toward the upstanding portions of the frame 12 somewhat past dead center, the upward- 1y extending arms of the frame 12 springing slightly from the container as the toggle passes dead center. The nozzle 18 and the drum are thus clamped firmly together and .to the swingable frame 12, with the parts in the position shown in Fig. 3.

To make it easy to apply a new'strip or strips of fabric to the apparatus, a plate or bar 50 is hinged at one end, as shown at 52 (Figs. 2 and 5), to one side of the nozzle.

adjustable set screw 56 threaded into a lug 58 projecting from the hinge 52 and bearin against a portion of the exterior surface 0 the nozzle, as shown in Fig. 5. To the other side of the nozzle 18 a latch 60 is pivoted at 62 and is normally held by a compression spring 64 (Fig. 5) in latching engagement with a shoulder 66 formed on or secured to the nozzle 18, thereby maintaining the plate in the position shown in Figs. 1 and 5.in which it serves to support the stri material 20 as the latter is drawn past the nozzle. When the container 16 is positioned open end upward, as shown in Figs. 3 and 4, the latch may be released by pulling upwardl upon a projecting portion or handle 68 t ereof, thus compressing the spring 64 andreleasing the latch from the shoulder 66 so that by continued upward swinging movement the plate 50 may be swung into the position shown in Fig. 2, in which position it is supported by a finger 70 projecting from the hinge 52 and shown particularly in Figs. 3 and 5. With the parts in this .position the strip material, a roll 72 of which may be supported on standards 74 located either on the floor, as indicated in Fi 4, or on a bench, with the apparatus, is gui ed to the apparatus by a suitable guide or guides 76, each, as illustrated, comprising a pair of parallel rods or rolls placed a short distance apart and between which the strip material passes. From the guides 7 6 the strip 'is passed through the space between the bar of the swingable frame 12 and the adjacent portion of the stationary frame 10 and then upwardly above the nozzle 18 and is rested upon the outlet of the nozzle 18 after which the bar 50 is swung downwardly and latched in the position shown in Figs. 3 and 4. The frame 12 is then swung through 180 about its trunnions 28 into the position shown in Fig. 1

whereupon the operator may seize the end of the strip 20 and pull it through the apparatus which will apply the coating material to the upper side of the strip.

Preferably and as illustrated the apparatus is provided with mechanism, of the character disclosed in the Nash Patent No. 1,771.388

previously referred to, to control the application of the adhesive material to the strip. The illustrated apparatus, moreover, duplicates this mechanism and provides an additional means by which two strips of varying widths may conveniently be, handled by the same apparatus. Thus the nozzle is provided with a pair of adjustable stripper plates (Figs. 1, 3, 5 and 6) and with a corresponding pair of deflectors 82 adjustable to control the thickness of the coating applied. The opening for the strip of material pulled past the nozzle is in the form of a narrow slot the lower wall of which is formed by the plate 50, and the upper wall of which is formed at the rear (as viewed'in Fig. 1) by the cast'metal of the nozzle 18 and at the front by the stripper plates 80, as indicated in Figs. 2 and 6. The outlet of the nozzle is divided into two portions by a closure shown as a block 84 secured b a screw 86 to a bridge formed in the nozz e. The block 84 projects upwardly from the casting of the nozzle so as substantially to contact with the plate 50 thus also dividing the slot into two parts for the reception of separate strips of material 20, forming guides for the adjacent edges of the two strips, and protecting the edge portions of the upper surfaces of the strips from the adhesive material. By utilizing the appropriate one of a series of blocks 84 the apparatus can be adapted to handle strips of any two of the widths which it may be desired to use.

. To maintain the swingable frame 12 in can-receiving position or in operative posit1on as may be desired, a latch 90 provided with a plunger 92 is-pivoted at 94 to the stationary frame 10. The latch 90 is normally held by a spring 96 with the plunger 92 in one or the other of a pair of holes 98 and 100 drilled in the swingable frame 12, one or the other of these holes being in alinement with the plunger 92 according as the swingable frame is in one position or the other. To facilitate the operation of the latch 90, the swingable frame 12 is provided with a pair of inclined cam surfaces 102 and 104 (best shown in Fig. 2) adjacent to the holes 98, 100 which serve to cam the plunger 92 outwardly against the action of the spring 96 as the plunger reaches the hole, thereby relieving the operator of the necessity of maintaining pressure on the handle of the latch 90 as the container and swingable frame 12 are swung from one position to another.

- A fpair of leather-faced bumpers 101, 103, are ormed on or secured to the swingable frame 12, in such position that one or the other will contact with the stationary frame 10 as the frame 12 is swung from one position to the other.

In order to permit air to enter the can 16 as the adhesive is used, a. small hole may be punched in the bottom of the can with the aid, for example, of a tool such as that shown in Fig. 7 and comprising a heavy, for example cast iron,handle 106 adapted to be held in the hand of an operator, an end of which is provided with a spur 108. The weight of the tool is such that it can be grasped in the hand and slammed downwardly against the upturned bottom of the can, which at the time should be in the operative position shown in Fig. 1, thereby causing the spur 108 to go through the ,bottom of the can and forming a hole to let in air. If at any time it is desired to remove the can from the apparatus before its contents have been completely utilized the hole thus formed may 'be stopped up by covering it with a small piece of the strip material to which the adhesive has been applied.
